摘要
本文从人类工效学的角度对作业环境微气候对伐木作业人员及作业效率的影响进行了理论分析和部分实例探讨。首先,作者对高温作业 环境的影响进行了热平衡分析和实例分析研究;其次,作者又对低温作业环境对作业人员及作业效率的影响进行了较深入的理论分析和实例探讨。结果表明,作业环境微气候对伐木作业效率有较为显著的影响。对北方林区而言,夏季高温环境(较正常环境)影响伐木作业效率幅度约为20％—30％,冬季低温影响幅度约为15％—25％。
Based on ergonomics, the paper made theoretical analysis and gave some examples to analyze the influence of microcosmic climate of working environment on felling worker and working efficiency. First, the author made heat equilibrium analysis and analyzed some examples to the influence of high temperature working environment; Next, the author made deep theoretical analysis and example discuss to the influence of low temperature working environment on workers and working efficiency. It indicated that microcosmic climate of working environment had marked influence on felling efficiency. For north forestry area, the influencing range of summer high temperature environment (comparing with normal environment) to working efficiency was 20%-30% and the influencing range of winter low temperature environment was 15%-25%.
